Honeybees collected nectar from both species. Pollen was usually collected incidently while the bees foraged for nectar, but in one experiment, 48% of the honeybees actively collected canola pollen from B. napus. Honeybees foraging on B. campestris were observed to ‘cross-over’ 34–81% of...
Eusocial bees in particular must collect pollen and nectar rewards to survive, but most workers appear to mix collection of both rewards over their lifetimes. We asked whether bumblebees specialize over timescales shorter than their lifetime. We also explored factors that govern such patterns, and...
